[QUOTE=EdSawyer;1456274]Flashbulbs are the only way to do flash in combination with the focal-plane shutter. The FP shutter will not sync with an electronic flash. QUOTE]

Is that only applicable to the Speed Graphic? Other FP cameras such as SLRs sync but at relatively slow speed. Usually 1/60th but 1/125th applies to many and some Nikons as I understand it sync at 1/250th

What is different in the Speed Graphic's FP?
